As someone who has done immunological research on illegal drugs I can
tell you that you get the drug for free and this carefully controlled
substance can be used for research experiments. They do not allow
protocols on humans so all of our studies were on mice. Although we
worked mainly with morphine and cocaine I assume cannabis is also
available for serious research purposes in animals.. Animal models are
more useful than human since they decrease time of experiments,
variability of lifestyles and dosage variations.... Toxicities are more
easily studied as are lower level trials and withdrawal effects.....
